Device for securing a cell battery with improved contact

摘要

A structure for a timepiece includes a middle part and a back cover that confines an electronic or electrical module. The module includes a plate, at least one circuit with at least one electrical contact area, and a connecting contactor. The plate includes a compartment that is arranged to receive an electrical energy accumulator. The connecting contactor provides an electrical connection between the accumulator and the at least one contact area. The contactor is rigid and includes an elastic return that tends to return the contactor to a rest geometry. The contactor includes at least a first arm and at least a second arm that together form a clamp that presses the circuit and the accumulator towards each other.

1. A structure for a timepiece, said structure comprising:
a middle part; and a back cover for confining an electronic or electrical module, said module including
a plate, the plate including a compartment that is arranged to receive an electrical energy accumulator,at least one circuit with at least one electrical contact area, anda connecting contactor to provide an electrical connection between said accumulator and said at least one contact area, said contactor being rigid and comprising an elastic return means tending to return said contactor to a rest geometry, said contactor including at least a first arm and at least a second arm together forming a clamp for pressing said circuit and said accumulator towards each other, wherein said back cover is arranged to bear, via at least a first bearing surface, on at least a first complementary bearing surface of said first arm of said contactor, said first arm is arranged to bear, via a first electrical contact surface on said accumulator positioned in said compartment, and wherein said back cover is further arranged to bear, via at least one second bearing surface, on at least one second complementary bearing surface of said first arm of said contactor, so as to press said accumulator onto said plate.
